* [svn-r6400] Raymond Lu2003-02-121-1/+1
| | | | | | | | | | | Purpose: Change feature Description: Switch to Fletcher32 from Adler32 checksum Platforms tested: arabica, eirene, modi4 Misc. update: MANIFEST and RELEASE.txt updated.
* [svn-r6395] Purpose:Quincey Koziol2003-02-121-0/+15
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Break up the ~9350 line H5T.c module into smaller pieces, which contain code for a particular feature or support for a datatype class. This should make the "main" H5T code (still in H5T.c) easier to support, as well as removing some of the "minor" routines from the user applications which don't use them (my rough estimates show about 4% reduction (~30K on a FreeBSD machine) in optimized, staticly-linked binaries for very simple programs) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) Misc. update: Update MANIFEST
* [svn-r6383] Purpose:Quincey Koziol2003-02-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature for developers. Description: Added "function stack" tracing to library. This allows developers (there is no public API) to call H5FS_print within the library and get a listing of the functions traversed to reach that point in the library. Eventually, I may add support for reporting the parameters to each function also... Mainly for debugging parallel I/O programs, but I think it will come in handy in other cases also. The function stack tracking is controlled with a configure switch: --enable-funcstack, which defaults to enabled currently. When we branch for 1.6, we should change the default setting on the branch to be disabled. Also, added a destructor to the thread-specific keys when thread-safety is turned on in the library. Otherwise, they were leaking memory and causing difficult to debug errors in threaded programs (like the test/ttsafe test). Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) w/thread-safety enabled. Misc. update: Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h) Update release_docs/RELEASE with thread-safety bug fix.

* [svn-r6307] Purpose:Quincey Koziol2003-01-211-0/+2
| | | | | | | | | | | | | | | | | Bug fix Description: Currently, when the library encounters an object header message that isn't know, it fails to open that object in the file. Solution: Allow the library to skip over the unknown object header message and continue to process the remaining messages, in the hope that the skipped message isn't important later. If it is important, it will be caught at a higher level of the library. Platforms tested: FreeBSD 4.7 (sleipnir)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

* [svn-r5940] Elena Pourmal2002-09-231-3/+4
| | | | | | | | | | | | | | | | | | | | Purpose: Bug fix, code improvement Description: Fortran tests didn't cleanup created files. Also HDF5_PREFIX and HDF5_PARAPREFIX were not used to specify location of the files. There was a redundant file in the testpar directory that contained an error reporting function used by both serial and parallel tests. Solution: Created library h5test_fortran.a that contains functions used by the serial and parallel tests. It includes Fortran and C functions that may be called from Fortran programs to report errors, to modify file names and to cleanup files after run. Modified test code to use new functions. Platforms tested: Linux 2.2 (eirene) serial IRIX64 (modi4) parallel with HDF5_PREFIX and HDF5_PARAPREFIX set to $SCR Solris 2.7 with mpich 1.2.4 with HDF5_PARAPREFIX set to /tmp/epourmal

* [svn-r5235] Purpose:Bill Wendling2002-04-231-0/+1
| | | | | | | | | | | | | | | | Update Description: Updated the way we used the AC_INIT macros so that it's current to the new standard way and not deprecated anymore. Also, added a test for some functions during parallel Fortran configure. This required the creation of an H5config_fortran.h file so that we can test for these... Platforms tested: Elena is going to test the changes to the fortran after she checks in her other code. I will test on SDSC machines after getting her code. The other changes were tested on Linux.
